In the video above, by WNYC’s Radio Rookies, four Caribbean teenagers make it their mission to learn about their Lubavitch Jewish neighbors in the Brooklyn neighborhood of Crown Heights. Their quest was inspired in part by the Ippies-award-winning documentary, “Living Apart in Crown Heights,” by the Jewish Daily Forward, about the legacy of the violent riots between Jews and Caribbeans 20 years ago.

“With our presence, we want to respond to the growing abuse of our countrymen,” said Damian Guadalupe Martinez, founder of the group, which plays their music in the Tzotzil language spoken in the region of Zinacatán, in Chiapas, Mexico. “We do know that indigenous peoples are entitled to retain their roots, their culture and express themselves freely.”

The band performed earlier this month at the United Nation’s Permanent Global Forum on Indigenous Issues, and has several other events lined up, including performances this weekend at Hostos College in the Bronx, and at Cinco de Mayo celebrations at Flushing Meadows Park and Sunset Park.

* El Diario La Prensa reported on a new study linking low literacy and math proficiency with parental errors in administering medicines to their children:

Parents whose math skills are at a third grade level or below are five times more prone to medication errors in children, a study by the American Academy of Pediatrics found.

The research, by H. Shonna Yin, at the New York University School of Medicine, indicates that these parents are more likely to measure the wrong amount of drugs than those with sixth-grade or higher math skills.

Parents with limited reading skills are also more prone to medication errors, previous studies have found.

Come autumn, Sunset Park will be home to the world’s largest rooftop farm on 100,000 square feet of space atop the historic Federal Building #2, located between Second and Third Avenues from 30th to 32nd Streets.

Designed and managed by BrightFarms, a New York-based development company, the 2.3 acre hydroponic farm will grow up to one million pounds of produce per year – enough to feed 5,000 people – to be sold to local supermarkets and other vendors. Its first harvest – of lettuces, tomatoes and herbs – is slated for spring 2013.
